元器件生意业务网讯 4月17日新闻,据外媒报导,飞思卡我半导体公司的Kinetis V系列微节制器将绑缚电机把持设想对象。

那款KV4x微掌握器散成了一枚150MHz ARM Cortex-M4处理器取浮面运算单位联合,经由过程128位宽的接心履行最高256Kb的闪存,从而削减CPU等候时光。

无传感器机电速率、地位检测圆里,两枚12位模仿数字转换器支撑下达1.9MS/s的抽样率,能够衔接包含计时器、模拟比拟器及GPIO正在内的微处置器外部中设穿插开闭。

Freescale Semiconductor’s Kinetis V seriesof microcontrollers come with a bundled motor control design tool.

Intended for sensored and sensorless motorcontrol designs,www.8469.com, requiring precise speed and position measurement in parallelwith general application task processing, the MCU supports a range of controlalgorithms from entry level BLDC to advanced PMSM and ACIM control loops.

The likely applications range from low-endpool pumps to more advanced robotics.

The KV4x MCUs incorporate a 150MHz ARMCortex-M4 processor with floating-point unit executing from up to 256kbyte offlash memory via a 128-bit wide interface that minimises CPU wait states.

For sensorless motor control speed/positiondetection, two 12-bit ADCs support sample rates of up to 1.9MS/s and can betriggered by any module connected to the MCU’s internal peripheral crossbar,including timers, analogue comparators or GPIO.

The KV3x family, also Cortex-M4 based,targets intermediate PMSM applications with CPU frequencies of 100-120MHz, upto 512/96kbyte of flash/SRAM.

The KV1x family represents the entry-levelof the series with a Cortex-M0+ MCU core.
